With reference to the drawings, I have illustrated my invention ascomprising mainly. an upper set oif: horizontal rails ill; a lower setof morizontal ra-ils ll, and the :asseciatedawertical snimal retainingslats i2 and fl.

The lower set of rails ll comprises the two rails I4which'arepennanentlyjoined together at them ends and arez'spa'eed fromeach other byiithee spacers I 6 -.to1provideothe slatreciiiin slot l1,and the cooperating clamping rail 15. The slot l1 receives the lowerends of the slats l2 and 13, the slat l2 being pivoted therein by thebolt l8 and the slat l3 being pivoted therein by the bolt IS, the twobolts l8 and I9 passing 32 v through openings'in -the rails 14-'andxbeing permanently securedtherein.

Associated with the bolt? l8; as shown Figure 6; is 'afspacer.sleeve"l8a.""The'"bolt19 isa'iso provided with one of thesetspacers Isa."fiThese spacers "I 8a and *l9af (Figure 2) keep. the two rails "14'properly spaced to provide'the slot1 1.. The unit formed by the'ra'ilsI4 (Figure zriis adapted tobe disposed at onesideiofithe jambs J of theopening'and theirail lfiis adapted "to be disposed at the other side'ofthe jambs. "These meinbers are connected in jainb clamping relationship'by'the clamping bolt units :20.""Each 'of thes units comprises a. boltwhich passes throughiali'gning longitudinal; slots 2:! in the rails 14and a's1ot'i22 in the 'raill5. I To adjust for different thicknesses of.jam'bs the 1 one end "of the bolt is provided with a series oflongitudinally spaced transverse 'bores23 for. receiving a locking pin24, which will retain on the bolt a washer?! adapt'edtto engage theouter rail I l. The other end'lof'th'e bolt, which is adjacentthe; r'ail'15, is provided with a wing nut 26 and an associated washer 21whichengages the'rail l5. Obvious- 13;" thebolt unit can be adjusted'byiresetting ZA'TOr-jamb's of di'iierenti thicknesses. Further!- more,it can-Abe adjusted in slots '21 and22 along the r'a'ils"l4 and I5 inaccordance withithe width of the, opening.

iThe upper set" of .rails'. (Figure4) is similar 'to the lower set! I,and includes the two joined rails 14a which are spaced by spacers 16a,,the associated clamping rail a, and 'theadjustable clamping bolt units20a with the. wing nuts"a and ool'l'ars'2il-a."The upper ends. ofthe'slats I2 and T3 'projectupwardly through the slotl'lfla. 'Ifheslatilz is provided withlani outwardly turned bayonet slot 18b atitslower end and theis'la't P3 is providedwithanloutwardlyturned-bayonet slot'il'Bb at its lower end which engagewijthi'the sleeves'ilfla andi'Qa, respeo'tiilely,- of the b'oltSTlB and"Iain 'p'ii'loting the slats'to the lowerra'ilunit Il.

""To automatically swing the upper e'nds'of the slats-i2and'l31outwardly, tension springs 28 and 28 ('Figure1) areanch'ored attheir lowene'nds to the outer ends-of"the.spaoedlra'ilsliand at their:upper ends #to the outer edges ofithe respective slats [2 ahd13, beinganchored in channels 30 and'Bl in theedges of the respective slats. Thebolt units -lflawserve as stops to limit butward swinging movementsofthe .slats :H and 113. Inward swinging movement of the slat I3 islimited by a transverse bolt 36 mounted in rails Mu but no means isprovided for limiting inward swinging movement of slat I2. Bolt 36carries a spacer sleeve 36a (Figure 4) to maintain the spacing of railsMa. If desired, for example when the stanchion is being used on smallanimals, a removable eye pin 35 may be inserted in transverse openingsin rails I la to hold the slat I3 vertical, engaging its outer edge toprevent outward swinging of this slat by the spring 29.

The slats I2 and I3 may be swung into operative relationship to retainthe head of an animal by means of a rope 32 which is anchored to theupper end of the slat I3 and which slides through an opening in theupper end of. the slat I2. openings 31 and 38 in the lower portions ofthe respective slats l2 and I3 for use in lifting the lower ends of theslats from the slot I! of the lower rail unit II when desired.

With the stanchion mounted on the door opening as indicated, the upperends of the two slats I2 and I3 will normally be spread apart by theaction of the springs 28 and 29 or the spring 28 alone. Both slats willcontact the bolts 20a, or slat I2, as shown in Figure 1, will contactbolt 20a. and slat I3 will contact pin 35. Obviously pin 35 will beremoved if it is desired to spread the upper ends of slats I2 and I3 tomaximum width. An animal can insert its head through the space betweenthe slats I2 and I3 and then the slats can be pulled towards each otherby means of the rop 32 to prevent withdrawal of the head. This rope maybe sufficiently long so that the stanchion can be operated from a remotelocation. The rope 32 may be reversed. Anchoring cleats 40 are providedat each end of the rail unit In for anchoring the end of the rope tohold the slats together. As soon as the rope is released, the slats willautomatically spread and permit withdrawal of the animals head. Aspointed out above, pin 35 may be removed to permit maximum spreading ofslats I2 'and I3. The spacing of the lower ends of the slats may beincreased by lifting the bayonet slots I81) and I9b from the bolts I8and I9 and permitting th springs 28 and 29 to pull their lower endsoutwardly into contact with the bolt units 20, as shown by the dottedlines in Figure 5. This allows a spacing practically the full width ofthe door opening for large cattle to pass through. Springs 28 and 29will hold the slats in fully opened position after the animal passesthrough. To narrow this spacing one or more of the slats may bepositioned inside the bolts I8 and I9 as also shown in this figure bydotted lines. This is desirable for small animals.

The provision of the bayonet slots is important as it prevents theanimal from raising the slats I2 and I3 out of the rail unit Il sincethe outwardly directed ends l! (Figure 7) of the slots will be inengagement with the spacer sleeves I82) and I913. The spreading effecton the lower ends of the slats I2 and I3 by the animal will cause theengagement of ends 4! with the sleeves. When the animal is removed, thelower ends of the slats I2 and I3 may be pulled inwardly to position thevertical parts 42 of the bayonet slots in alignment with the spacersleeves l8a and I9a. At this time, the slats I2 and !3 may be liftedfrom rail unit H by the ropes 33 and 34. Instead of ropes 33 and 34, thepin 35 may be used with openings 3'1 and 38 (Figure 5) to lift the slatsl2 and I3 out of the slot 11.

Other ropes 33 and 34 may be anchored in' The stanchion can be removedfrom the open ing easily by removing the bolt units 20 and 20a. It canbe knocked-down by lifting the slats I2 and I3 from the rail unit I Iand pulling them out of rail unit I0. It is merely necessary to removewing nuts 26 and 26a and no tools will be required. My device can thenbe transported easily in knocked-down condition and obviously can beset-up readily in a different opening. The stanchion can be adjustedreadily to fit openings of different widths and jambs of differentthicknesses.

Various other advantages will be apparent.

Having thus described my invention, what I claim is:

r .1. A stanchion comprising upper and lower rail units including railsadapted to be clamped at opposite sides of vertical supports, connectingmembers in the form of clamping bolt units for holding said rails inclamping relationship, said lower rail unit including a pair of railsdisposed atone side of the vertical supports and a single rail at theopposite side of the supports, relatively adjustable slats pivoted in aspace between said pair of rails by means of bayonet slots in the slatsand pins carried by said rails, said upper rail unit also including apair of rails disposed at one side of the vertical supports and a singlerail unit at the opposite side of the supports and being connected bybolt units, said slats extending upwardly between the pair of rails ofthe upper rail unit and being free to swing in the space providedtherebetween, springs connected to the slats and anchored to the lowerrail unit for normally swinging said slats apart, said bolt units of theupper rail unit serving to limit outward swinging movement of saidslats, a rope anchored to the free end of one of said slats and slidablyconnected to the free end of the other to pull said slats towards eachother, a stop pin carried by the upper rail unit for'limiting inwardswinging movement of one of said slats, and a removable pin carried bysaid upper rail for limiting outward swinging of said slat.

2. A stanchion according to claim 1 wherein each of the bolt units isadjustable as to length to clamp the rails to vertical supports ofvarying thicknesses.

3. A stanchion according to claim 2 wherein each of the bolt unitspasses through longitudinal slots in the rails of the rail units.

4. A stanchion according to claim 3 wherein said removable pinis spacedfrom said stop pin to limit outward swinging movement of the associatedslat.
